Multiquip 6216545420 Oil Cap DCA400SSK SA6D140E-2

The Multiquip 6216545420 Oil Cap DCA400SSK SA6D140E-2 is a genuine OEM component designed for the DCA400SSK ultra-silent diesel generator series. Sourced directly from Multiquip, this oil cap is an exact-match replacement engineered to the original specification for the SA6D140E-2 engine fitted to DCA400SSK units. Keeping this component in service-ready condition is essential to maintaining proper engine lubrication integrity on these high-output generator sets. Confirm your model and engine code against your serial plate before ordering to ensure a correct fit.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the original closure and thread specification for the SA6D140E-2 engine, ensuring a proper oil-tight seal every time the cap is seated.
• Direct Drop-In Replacement — Matches the original thread pattern and cap geometry on DCA400SSK engine fill ports, seating correctly without rework or modification to the oil fill neck.
• Confirmed DCA400SSK Fitment — Verified for the DCA400SSK ultra-silent diesel generator equipped with the SA6D140E-2 engine; always cross-reference your engine nameplate before ordering.
• Protects Engine Lubrication System — A correctly seated oil cap prevents contamination ingress and maintains crankcase pressure balance, both critical to long engine service life on high-hour generator applications.
• Fuel and Oil Resistant Material — Constructed from materials rated for continuous contact with engine oil, resisting degradation from heat cycles and oil additives common in heavy-duty diesel engines.

The oil cap seals the engine's oil fill port and plays a direct role in maintaining crankcase pressure and keeping airborne debris and moisture out of the lubrication system. On a working generator like the DCA400SSK, a damaged or improperly seating cap can allow oil contamination that accelerates wear across bearings, pistons, and seals. Replacing a worn or cracked cap promptly with a genuine OEM part ensures the lubrication system continues to function as the engine manufacturer intended.
